Answer:
2.846m
Explanation:
The diver is performing projectile motion.
To find x(final), we are going to use the equation x(final) = v(initial)*t + x(initial)
x(initial) = 0
x(final) = ?
v(initial) = 2.3 m/s
we don't know t
To find t we will use y(final) = 1/2*(-9.8)*t^2 + v(initial in the y dir.)*t + y(initial)
- 9.8 in the acceleration in the y dir.
y(final) = 0
y(initial) = 7.5
v(initial in the y dir.) = 0
If we solve for t we get: t = 1.237s
Now we have all the components to solve for x(final) in x(final) = v(initial)*t + x(initial)
x(final) = 2.3*1.237 + 0
x(final) = 2.846m
In the centripetal movement, what happens with velocity is that it will remain constant, always pointing in its tangential direction of the trajectory. Said speed, although constant, will have a constant direction that will generate an acceleration that will always point towards the center of the circle radius. Both vectors as the turn is performed will always be perpendicular to each other.
Answer:
Kinetic energy of an object can't be greater than potential energy.
Explanation:
This is due to the reason that some of the energy is lost in the form of friction, heat energy, light energy etc. For example, a ball bounces to a height h in its first bounce.
<em>I am gonna have to say A 0.02 because 2 meters a second is way too fast 0.2 is a little more than reasonable and if 2 meters a second is too fast then 20 is off so</em> A. should be most reasonable
I don't know about hard to make, but it's impossible to make a mechanical wave transmit energy through a vacuum.
